A student launches a homemade rocket from the roof of his house. The trajectory of the rocket is represented by the function h = -0.5t² + 8t + 10, where h equals the height of the rocket (in feet) above the ground (after 5 seconds).

What is the maximum height reached by the rocket, in feet?

(a)  

A student launches a homemade rocket from the roof of his house. The trajectory of the rocket is represented by the function h = -0.5t² + 8t + 10, where h equals the height of the rocket (in feet) above the ground (after t seconds).

For how long is the rocket in motion (rounded to the nearest second)?

• 8 seconds

• 10 seconds

• 17 seconds

• 42 seconds

Solve for x.

Solve for x.

y = x² – 5x – 4

• x = (-5 + √41)/2; x = (-5 - √41)/2

• x = (5 + √9)/2; x = (5 - √9)/2

• There are no real solutions

• x = (5 + √41)/2; x = (5 - √41)/2
